Aluminium-Zink-Magnesium Coated Steel

Aluminium-Zink-Magnesium Coated Steel - 4 Times better than pre-galvanized steel*

A recent development in the steel market has been the advent of steel coated with a zinc, aluminium, magnesium alloy. This coating replaces the conventional 100% zinc or zinc-aluminium coating, offering much higher corrosion resistance for a similar price. These steels go under a variety of trade-names such as ZAM (Nippon), Magnelis(Arcelor Mittal) or are often simply referred to as Aluminium-Zink-Magnesium or "AZM" coated steel or Mg-steel.

Advantages of AZM Steel:
Superior Corrosion Resistance:

AZM steel, with its unique composition of aluminum, zinc, and magnesium, offers superior corrosion resistance compared to Z275 pre-galvanized steel. The protective barrier formed by AZM steel effectively shields against corrosion in diverse environments.

Enhanced Durability:

With the added alloying elements of zinc and magnesium, AZM steel exhibits enhanced durability. This alloy combination creates a robust protective layer, ensuring prolonged performance and reducing the risk of degradation over time.

Improved Galvanic Protection:

AZM steel provides improved galvanic protection compared to Z275 pre-galvanized steel. The presence of zinc and magnesium enhances the material's ability to protect the underlying steel substrate, even in the presence of moisture and other corrosive elements.

Excellent Barrier Properties:

The unique composition of AZM steel results in excellent barrier properties. It effectively prevents the penetration of moisture and corrosive substances, reducing the likelihood of rust formation and ensuring long-term structural integrity.

Versatile Applications:

AZM steel finds extensive use in various applications, including construction, automotive, agricultural, and infrastructure projects. Its superior corrosion resistance and durability make it suitable for roofing, cladding, structural components, electrical appliances, and more.

Lower Life-Cycle Costs:

Choosing AZM steel can lead to reduced life-cycle costs compared to Z275 pre-galvanized steel. Its exceptional corrosion resistance and prolonged durability result in longer service life, minimizing the need for maintenance, repairs, and replacements.

Environmental Sustainability:

AZM steel is an environmentally sustainable choice. It can be recycled, reducing the environmental impact associated with steel consumption. By opting for AZM steel from Tubecon, you contribute to a greener future while benefiting from its superior performance.
